My own opinion again, but classical psychopathic behaviour. He loves all the attention -- sees himself as some powerful mega star, and thinks he will win. Also something just plain evil, gloating and smiling like that at the grieving widow. If he has no ability to feel empathy or remorse, this is all a big game to him. He probably thinks everyone, including the pretty girls in the room, he also smiles at, are very impressed with him. Thank goodness LE took him off the streets when they did. This guy likely would have really enjoyed continuing as a serial killer. I think when he missed part of the turn, and pulled out the gun from its concealment holster, he just could hardly wait to shoot Tim. Evil beyond belief, and for a normal, moral person hard to get your mind around.
